.. index:: pair: page; SquaredDifference .. _doxid-dev_guide_op_squareddifference: SquaredDifference ================= General ~~~~~~~ SquaredDifference operation performs element-wise subtraction operation with two given tensors applying multi-directional broadcast rules, after that each result of the subtraction is squared. Before performing arithmetic operation, :math:`src_1` and :math:`src_2` are broadcasted if their shapes are different and ``auto_broadcast`` attributes is not ``none``. Broadcasting is performed according to ``auto_broadcast`` value. After broadcasting SquaredDifference does the following with the input tensors: .. math:: dst_i = (src\_1_i - src\_2_i)^2 Operation attributes ~~~~~~~~~~~~~~~~~~~~ =========================================================================================================================== ============================================================= ======= =============================== ========= Attribute Name Descr =========================================================================================================================== ============================================================= ======= =============================== ========= :ref:`auto_broadcast <doxid-classdnnl_1_1graph_1_1op_1ac7650c0c15849338f9c558f53ce82684a0624e198ec0ae510048b88ff934822cc>` Specifies rules used for auto-broadcasting of input tensors. string ``none`` , ``numpy`` (default) Optional =========================================================================================================================== ============================================================= ======= =============================== ========= Execution arguments ~~~~~~~~~~~~~~~~~~~ The inputs and outputs must be provided according to below index order when constructing an operation.
